The mapping of useful traits related to fruit quality using F2 self population and breeding of high quality cultivars in Pyrus

由于严格的配子体不亲和性，长幼期和高杂合性限制了梨的亲本组合。标记辅助选择（MAS）被认为是通过识别有利的遗传组合来提高选择效率的有力工具。在这项研究中，我们开发了蔗糖含量的DNA标记，负责改善味道。此外，还开发了与黑斑病和痂病抗性相关的DNA标记。这些标记对选育具有良好口感和抗病性的苗木有一定的参考价值。

A long juvenile phase and high level of heterozygosity due to a strict gametophytic incompatibility have limited the parental combinations in pear breeding programs. Marker-assisted selection(MAS) is considered to be a powerful tool for increasing selection efficiency by identifying favorable genetic combinations. In this research, we have developed DNA markers for sucrose content responsible for taste improvement. Moreover, DNA markers linked to black spot and scab resistance were developed. These markers should be useful for the selection of seedlings with good taste and disease resistance.
